When writing business reports for outsiders, a more formal tone is appropriate as it conveys a sense of professionalism and credibility. This helps to establish trust with the reader and assures them that the information provided is trustworthy. Using a less formal tone or sprinkling the writing with jargon or acronyms can confuse readers and may not be appropriate for all audiences. Headings, transitions, previews, and reviews can help guide the reader through the report and make it easier to understand. Starting the report by explaining why they need your help is not relevant for all reports and can be seen as self-promotion.
